- Adult: Broad, flat, shield-shaped bugs that are brown on top with a yellowish underside. About ½" long.
- Nymphs: Look similar to adults but lack wings.
- Eggs: Round, laid in clusters and orange with a ring of white hairlike structures on the top.
Timing of damage: VE to R3
Type of damage: Holes in the leaves that are often ringed in yellow. Tillering, wilting and plant death can also occur.

Economic threshold: There is no established threshold but treatment is most effective when
applied at or just after plant emergence.
